The National Progressive Unionist Rally Party (Arabic: حزب التجمع الوطني التقدمي الوحدوي, romanized: Ḥizb al-Tagammu' al-Watani al-Taqadomi al-Wahdawi, commonly referred to as Tagammu, meaning "Rally" in English) is a socialist political party in Egypt.

Originally known as the National Progressive Unionist Rally Organization, it was established as the left-wing faction of the governing Arab Socialist Union (ASU) and became an independent party after ASU's dissolution.

The party considers itself a defender of the principles of the Egyptian Revolution of 1952.

It calls for standing against attempts to reverse the revolution's social gains for labourers, the poor, and other low-income groups.
